   I use pcase often; but I use it just as a better cond. For example I find this
   handy:

   (defvar foo nil) <-- foo is some symbol

   (pcase foo
     ('bar (do-some-bar-stuff))
     ('baz (do-some-baz-fluff)))

cl-case seems more appropriate here (wish cl-case was just case ...)

   or this:

   (setq foo "some-string")

   (pcase foo
     ("foo" (do-foo-case))
     ("bar" (do-bar-case)))

Same here, with (intern foo) ...
